| Abstract: | Uniform distribution of pressure amplitude can be effected by the sets of values of frequency and phase for a three frequency acoustic field. The formula of average pressure and the mean difference of pressure are presented as function of frequency and phase; it is known that uniform distribution of pressure amplitude can be obtained by the sets of values of frequency and phase. |
